Toshiba Satellite Laptop Says RTC Battery Low?

RTC Battery is low means that the motherboard is unable to retain a charge. To replace you'll need a CMOS battery (CR2032) or more commonly referred to as a watch battery.

What is an RTC battery?

The RTC stands for the real-time clock, which is a small battery that keeps track of the current time even while the computer is turned off. A laptop's RTC battery usually runs on lithium coin cell batteries that are capable of holding the data for a specific time after your computer goes into Hibernation or Sleep mode. When you turn it back on, it resumes where it left off because these clock settings have been stored in RAM memory during sleep mode.

When your Toshiba Satellite shows the RTC battery low message, it tells you that this battery is nearing the end of its life and needs to be replaced very soon.

If you are not able to replace it yet, keep your Toshiba laptop plugged in a power source to charge the RTC battery. But we all know that batteries will soon lose their ability to hold a charge, and this means that even when your laptop is plugged in, it will not be able to maintain an actual power source if the battery dies.

Ignoring the issue will result in malfunctions and would cause problems with your daily use of the system. In the end, replacing the RTC battery will fix the problem and allow your Toshiba to run normally again.

If you are unable to replace the RTC battery yourself, it is best that you take your laptop to a service center for help. If there isn't any Toshiba service station nearby, then try finding one online or contact the manufacturer directly.

To prolong the RTC battery for best performance, make sure you let your laptop charge completely before using it and also try keeping it plugged in as much as possible when you are not actively working with it.

Where is the battery located on a Toshiba laptop?

The RTC battery in a Toshiba Satellite is located on the mainboard of the laptop. To access it, you will need to unscrew all the screws from the bottom of your laptop and remove the mainboard cover. Be very careful not to damage any other components in the laptop when you are doing this, as the other little components are sensitive and can be damaged easily.

When you are replacing the battery, make sure that you use a safe prying tool to pry out the old battery. Do not use any sharp tools or knives to do this. Insert the new battery gently, following the correct battery pattern. The positive side of the battery should be facing up. Make sure that you do not touch any other components in your laptop when replacing this battery, as it can cause damage to them if they are exposed to electricity or get short-circuited. Once you have replaced the battery connect all the screws back into place and turn on your computer.

How to reset the date and time in a Toshiba laptop?

Resetting the date and time to your Toshiba is an easy process. The main key that would help you restore this setting is by pressing the F2 button on your keyboard. You may need to recheck if your laptop model uses this key, as some other models will require you to press the Escape button rather than the F2 button. Once you have pressed the F2 button, the screen will show you where you can navigate and change the date and time setting. Once you have corrected the setting, don't forget to hit the save and exit button.

Conclusion

The Toshiba laptop is a very reliable computer, but like all electronic devices, it has its downsides, especially if its RTC battery has been left uncharged for an extended period of time. To avoid inconvenience and bad battery life, take care of the RTC battery and charge it often or replace it with a new one as soon as the RTC battery low message appears. If you are still encountering errors after replacing the RTC battery, you might want to schedule a visit to an authorized Toshiba repair center and let the experts handle it for you. This way, you can have your laptop fixed with the assurance that it will work perfectly well after the repair.
